One Piece, Volume. 18

The Straw Hats at long last reach Alabasta! But their stay is cut short when Luffy attracts too much attention from the Navy. They're not the only ones interested in Luffy--someone from his past has been waiting for him too! Meanwhile, the Baroque Works' agents are summoned together when their leader, the dastardly Mr. Zero, aka Sir Crocodile, learns that Luffy is still alive and orders his immediate extermination!
